Nitrogen Generation Packages
Industrial Nitrogen: Uses, Applications and On-Site Generation
September 28, 2026 Welcome
What does a facility actually need from its nitrogen supply? That depends on where the gas is going and how often it’s needed. Industrial nitrogen can serve a brief purge or run as part of a continuous process. This guide looks at common applications and when on-site generation may make sense.
Why is Nitrogen Used in Industrial Processes?
Nitrogen is used when a process needs a gas that reacts very little with other materials. It can displace oxygen in tanks, piping, and equipment, helping limit oxidation or reduce the conditions that allow a flammable mixture to form. The amount and quality of nitrogen needed depend on the process, which is why facilities specify more than a single purity number.
Common Industrial Uses of Nitrogen Gas
Tank Blanketing and Process Inerting
The non-reactive nature of nitrogen gas makes it useful in industrial processes where oxygen can cause problems. Facilities use nitrogen to blanket storage tanks and displace oxygen from process equipment. In applications involving flammable materials, this can help reduce the conditions needed for a fire, provided the system is designed and operated for that purpose.
Pipeline and Equipment Purging
Nitrogen can also be used to purge piping and equipment before startup, maintenance, or commissioning. The gas displaces air or other gases from the system so crews can prepare it for the next stage of work. IFS provides nitrogen generation packages for applications that include export line commissioning.
Oil and Gas Operations
Oil and gas facilities use nitrogen in several applications, including purging, inerting, and buffer gas supply. The required flow, pressure, and gas quality depend on the equipment and the job. IFS nitrogen generation packages can be engineered for offshore and onshore operations, including well servicing and buffer gas applications.
Nitrogen can also be used in some enhanced oil recovery projects, where gas is injected into a reservoir to help recover oil.
Food and Beverage Manufacturing
Nitrogen gas is used in several commercial food and beverage production processes. For example, it can be used in beverage sparging and in modified-atmosphere packaging to help preserve the freshness of packaged foods. These applications have their own gas quality requirements.
Electronics Manufacturing
Nitrogen is also used during some electronics manufacturing processes. During soldering, it can help limit oxidation around the components being joined. The nitrogen supply must meet the requirements of the specific process and equipment.
How is Industrial Nitrogen Generated On-Site?
The applications above need different amounts of nitrogen and different gas quality. When a facility needs a regular supply, an on-site nitrogen generation system can produce it from compressed air instead of relying entirely on deliveries.
IFS uses membrane technology in its nitrogen generation packages. After the compressed air is filtered and conditioned, it passes through hollow polymer fibers. Oxygen and other gases pass through the fibers more readily, leaving a nitrogen-rich stream for the process. Controls monitor the product gas, while feed air pressure, temperature, and the required oxygen content affect how much nitrogen the system can produce.
For a closer look at the equipment and other production methods, read IFS’s guide to how nitrogen gas is produced.
What Should You Know Before Choosing a Nitrogen Generation System?
Start with what the process needs: nitrogen flow, required purity, delivery pressure, and how often the system will run. Feed air quality, available space, and site conditions also affect the package design. If nitrogen serves more than one use, tell IFS which demands may occur at the same time. Those details help the team specify an engineered system for the facility.
